Clover Seed

Red clover (Trifolium pratense L.) was grown for seed production after the seeding year on two different types of soils, in the same climatic area. An important difference in yield which was often related to cultivar and sometimes to year was observed between the two soils — the light soil, Saint-André gravelly loam, produced more seed than the heavy Kamouraska clay. Seed yield differed between cultivars with Florex and Arlington producing the most. On an annual basis, the thousand-grain weight was higher on Kamouraska than on Saint-André. The percent germination was not influenced by soil type and cultivar but variation between years was observed. The production of heads per plant was higher on Saint-André. The number of seeds produced per plant and per head was, as for yield, higher on Saint-André than Kamouraska. The influence of cultivars and years was not always visible on these last parameters. Therefore these results demonstrate that generally the success of red clover seed production depends not only on cultivar and climatic conditions, but that within the same climatic area the type of soil is a major factor. Key words: Red clover, seed production, soil effect, year of harvest, cultivar, yield components

The clover seed weevils, <em>Apion trifolii</em> and <em>Protapion apricans</em>, members of the genus Apion, are responsible for causing serious economic damage in clover. In 2010-2012, the effectiveness of some insecticides against clover seed weevils in the genus <em>Apion</em> were tested in red clover stands. The efficacy of different products was evaluated on the basis of analyses of specimens trapped in the herb layer of red clover using a sweep net and red clover heads sampled in individual plots. Over the course of these trials, the applications of the products tested resulted in a marked reduction in their numbers (particularly of adults and, to a lesser extent, also of larvae). The highest efficacy was observed with Biscaya 240 (A.I. thiacloprid) and Mospilan 20 SP (A.I. acetamiprid). Results obtained in this study corroborated the low efficacy of the insecticide Karate Zeon Technology 5 CS against seed weevils of the genus <em>Apion</em>.

Clover Seed

Red clover (Trifolium pratense L.) is one of the most important forage legumes in areas with acidic and nutrient poorer soils where alfalfa fails to growth. In 2010-2011 years period we studied four advanced lines and four commercial varieties of red clover, which are widely used in the production in Bosnia and Herzegovina. Our results showed that the variation in grain yield, thousand kernel weight and germination energy was under control of growth. Across genotypes seed yield in 2010 and 2011 was 205 and 223 kg ha-1, respectively. The highest yield of seed was obtained from second growth in the second year. Extreme precipitation during anthesis and grain filling and ripening in 2010 negatively affected red clover seed production. Advanced line DS-2 had the highest grain yield (234 kg ha-1) and thousand kernel weight (1.75 g). Low seeds yields of the tested genotypes are questioning the cost-effectiveness of red clover seed production at this site.
